Description

Technical Field

[0001] The utility model relates to the technical field of product filling, in particular to an automatic filling structure for liquid products. Background Art

[0002] As an important by-product of air separation equipment, cryogenic liquid products have a huge impact on the energy consumption and efficiency of air separation units. With the continuous development of air separation technology, the size of air separation equipment is also increasing, and the production capacity of liquid products is also increasing.

[0003] The filling of cryogenic liquids is different from general filling. It is affected by the purity and temperature of the medium. It is necessary to analyze the purity of the residual medium in the tank truck before filling; after filling, analyze the medium in the tank truck to ensure that the product purity meets the requirements, and so on.

[0004] During the current factory liquid product filling process, the pre-filling and post-filling analysis of the medium in the tank truck is done manually, which is time-consuming. Operators are required to supervise the site from the start of filling until the filling is completed. During periods of high liquid sales, tank trucks for various products are filled frequently, factory operators are stressed and inefficient, and there is also a risk of frostbite during the filling process.

[0005] For this reason, we propose a liquid product automatic filling structure to solve the existing problems. Utility Model Content

[0006] The purpose of the utility model is to propose an automatic filling structure for liquid products in view of the problems existing in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic filling structure for liquid products, comprising a filling tube, a cylinder and a fixing frame, the filling tube being connected with a connecting tube, the cylinder being installed on the connecting tube, a piston being slidably installed in the cylinder, and a discharge port being opened at one end of the cylinder close to the connecting tube, and a detection tube being installed on the discharge port.

[0008] Preferably, connectors are installed at both ends of the filling tube;

[0009] Control valves are installed on the connecting pipe and the detection pipe.

[0010] Preferably, a fixing frame is installed on the outer wall of the cylinder through bolts, a notch is opened at one end of the fixing frame, and a gear is rotatably installed on the notch;

[0011] A plug rod is installed on the end surface of the piston, and a rack is installed on the outer wall of the plug rod through bolts;

[0012] The gear and the rack are in a gear-meshing state.

[0013] Preferably, the outer surface of the fixing frame is mounted to the chassis by bolts;

[0014] A motor is fixed in the chassis by bolts, and the output end of the motor is connected to the shaft end of the gear.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] During use of the automatic filling structure for liquid products of the utility model, one end of the filling pipe of the device can be connected to the inlet of the tank truck to be filled, and the other end of the filling pipe can be connected to the output end of the external filling pump;

[0017] When sampling and testing the medium inside the tank truck before filling, the control valve on the detection tube and the connection end between the filling tube and the filling pump are closed, and then the motor is controlled to drive the gear to rotate, and the meshing action between the gear and the rack drives the piston to move, so that negative pressure is generated inside the cylinder, thereby pumping the residual medium inside the tank truck into the cylinder;

[0018] Then close the control valve of the connecting pipe and open the detection tube. At this time, control the gear to reverse, and the medium inside the cylinder can be pressed into the detection tube through the piston. Then, the detection tube is connected to the external medium real-time detection device for detection. After the medium is filled, reasonable operations can be performed in the above manner.

[0019] The utility model automatically completes sampling of the medium in the tank truck before and after filling, thereby improving the filling efficiency, reducing the pressure on operators, and improving the filling safety and stability. BRIEF DESCRIPTION OF THE DRAWINGS
